PHONOGRAPHIC-RECORD-CLEANING DEVICE.

Specification of Letters Patent.

Patented Nov. 8, 1921..

Application filed October 27, 1917. Serial No. 198,816.

To all whom it may concern Be it known that I, LEONARD A. lVELLIXo- TON, a citizen of the United States, residing at Keene, in the county of Cheshire and State of New Hampshire, has invented certain new and useful Improvements in; Phonographic-Record-Cleaning Devices, of which the following is a specification.

This invention relates to a cleaning means for removing particles of dust from the sound grooves of a phonograph record.

The object of my invention is to provide a cleaning brush of soft material which is mounted in such a manner as to be moved across the face of the disk or sound record during the playing of the same.

Another object of my invention is to provide means for the vertical adjustment of said brush to accommodate the same to different machines which may vary somewhat as to the height of the sound record.

In the accompanying drawings Figure 1 is a top plan view showing my device as applied,

Fig. 2 is a side elevation of the device,

Fig. 3 is an enlarged horizontally vertical section through the pivotable point and adjusting means,

Fig. 4 is an enlarged top plan view of the inner end of the roller support, and

Fig. 5 is a modified form disclosing a different form of means for mounting the device upon the machine.

Numeral 1 indicates the base upon which is mounted a supporting member 2. This supporting member preferably consists of a single strrp, which as shown, is bent back upon itself as at 3, the outer end of the under portion being bent up slightly and provided with an orifice 5, the remaining free end being bent vertically from the main portion and again bent horizontally as at 6, and extending somewhat beyond the lower end 4. This portion 6 is also provided with an orifice 7, which is in vertical alinement with the orifice 5 in the lower portion, thereby forming a vertical support for a supporting member 8, the stem 9 of which is received within the orifices at and 7.

Pivoted to the support as at 10 for vertical movement is a resilient arm 11, the inner end of which is bent up into a substantial U shaped form and adapted to surround the vertical support 8. Mounted at the outer end of this resilient arm 11 is a padded cleaning roller 12 which is rotatably supported thereon by means of a stud 13 passing through the roller and an orifice 14: in the arm, and is provided with an adjusting nut 15, whereby the roller may be held frictionally fro-m rotation with the dish and yet be turned manually to different positions to present different portions of the padded periphery to the disk. The arm 11 is extended beyond the roller and bent up hook-fashion providing a means for manipulating manually the above mentioned arm.

In order to accommodate this device to different machines wherein the height from the base of the support to the surface of the record may vary, I have provided an adjusting means which preferably consists of a vertically arranged adjusting screw 16, mounted in the outer end 6 of the member 2. This screw is adapted to pass up through the looped end of the arm 11 and through a plate 17, which is provided with flanges 19. This plate is provided with a semi-circular opening 19 which is adapted to receive the adjusting screw 16 on the outer end of which is secured, threaded and provided with an adjusting nut 20. The semicircular opening 19 permits of a certain rotary movement of the arm 11, which permits the padded roller to be carried inwardly between the grooves on the record as the same is being rotated.

It is obvious that the support for the roller may be fastened other than the method shown, as for instance, the base of the support may be of sufficient weight to hold the roller by sheer weight, or as disclosed in Fig. 5, wherein the supporting member 8 is journaled on a stud 20 which is slidably mounted upon one of the jaws of a clamping member 21. These jaws 22 and 23 of the clamping members are provided near their outer ends with elongated slots 24 which are adapted to receive the lower portion of the supporting stud 20, being provided on its lower end with an adjusting nut 25. A plate 26 secured to this stud 20 which is of such a width as to be received between the flanged sides of the upper jaw 22. Arranged vertically on this plate is an adjusting screw 16 which is identically in operation as an adjusting screw 16, described in the preferred form.

From the above it will be observed that I have devised a very simple device which is simple in construction, yet very effective in manlpulation, and one which can be manufactured very cheaply.

I claim:

1. A phonographic cleaning device comprising a needle support of universal movement, and a cleaning device carried by said support and adjustably therewith, the cleaning device fed from the record by the action of the grooves of the record, whereby its position changes with reference to the record.

2. A phonographic record cleaning device consisting of a base, and an arm carried thereby free to'swing both horizontally and vertically on suitable pivots, and a cleaning roller mounted at the outer end thereof.

3. A phonographic record cleaning device consisting of a base, a stud pivotally mounted thereon, an arm pivotally mounted on said stud, said arm free to swing both horizontally and vertically and provided at its outer free end with a cleaning roller.

4:. A phonographic cleaning device supported at one end upon some fixed part of the phonograph and at the cleaning end upon the record whereby it is fed from the record by the grooves just as the needle is fed.

5. A phonographic cleaning device having a universal joint support at one end and resting at the cleaning end in the groove of the record by which it is fed from the surface of the record.

6. A phonographic cleaning device including an arm, a universal joint at one end of the arm connected with some fixed part of the phonograph and a cleaning device rotatably and adjustably connected with the carried thereby, a pivoted stud arranged ver tically therein, a horizontally arranged arm pivoted to said stud, a cleaning roller carried at the outer free end of said arm, an adjusting screw carried by said supporting member adapted to engage the other end of said horizontally arranged arm whereby the cleaning roller may be adjusted to different heights.

8. The combination with a suitable support, of an arm adapted to rest horizontally over a phonographic record, and supported entirely independent of the tone armor needle support, and a record cleaning device carried by said arm and adapted to rest with frictional contact upon the record, and be fed across the record by the grooves of the latter.

9. The combination with a suitable support, of an arm adapted to rest horizontally over a phonographic record, and a record cleaning 7 device carried by said arm and adapted to rest with frictional contact upon the record, said cleaning device being re settahle upon the arm to present a new cleaning surface to the record.

In testimony whereof I aflix my signature.
